- UNITED STATES PATENT OFFICE.

PETER G. NEISENDORFER, OF BALTIMORE, MARYLAND.

COMBINED BUNG-BUSH AND STAMP-PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 286,474, dated October 9, 1883.

' Application filed February 19, 1883. (No model.)

To all whom it may concern:

Be it known that I, PETER GEORGE N151} snnnonnnn, of Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Combined Bung Bush and Stamp -Proteetor; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Figure 1 is a vertical section taken centrally through the improved bung bushing and its hinged covering-ring, showing the spring-bolt applied to said ring, and in section also showing a revenue-stamp applied to said parts with a hung inserted. Fig. 2 is a top view of the device, showing the hinged covering-ring thrown back.

This invention relates to bushings for beerbarrels, and also to a combination with such bushings of seats and coverings for the seats, whereby revenue-stamps are protected on the barrels after they are canceled; and the nature of my invention consists in a hinged capping-ring, a cup-shaped cap for a bushing, and a spring-holder for the capping-ring; also, of spurs on the flanged capping portion of the bushing, all of which will be fully understood from the following description when taken in connection with the annexed drawings.

A designates a tubewhich is internally beveled so that it flares outwardly with respect to the barrel when applied thereto, and which has a male screw cut on it. This tube is made of metal, and it is cast with a flange, a, at its upper end, which flange has a rim, 6, partly surrounding it. At the terminus of the rim 1) are cast eyes I) 1), adapted to receive through them a pintle, If, which forms a hinge andunites a ring-cap, B, to the bushing. Inside of the flange of the rim b of the bushing, and east integral therewith, are two lugs, Z l, and at right angles thereto, on one side, a bowspring, S, is applied, opposite which a recess, 5 is made into the flange, and in a direct line with this recess a perforated lip, h, is raised At the point indicated by the letter 9 a tubular enlargement is made on the cappingring B, and in which a coiled spring, 8, is ap plied, the object of which is to act on a bolt; b, which has a beveled nose adapted to enter the perforated lip h on the rim of the bushing.

Now, when the ring is shut it lies flush within the rim 2/, and is locked snugly therein by the spring-bolt b", above referred to.

The main object which I have in view isto prevent any portion of a revenue-stamp, when applied to a beer-barrel, from being so oblittion can be effected not only by the closing of the hinged ring-cap, but also by the introduction of the bung into the barrel through said ring-cap; and it will also be seen that while said advantages are obtained, I also have the further advantage of preventing the canceled parts of the United States revenue stamp from being washed or rubbed from the parts surrounding the outside of the bung of the barrel. I

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A bung-bush consisting of a tubular external screw -threaded portion having a tapered bore and a flange which is cup-shaped, a cap having ahole through its centenaspringactuated bolt for locking the cap down in place in said cup, and a spring for throwing up the cap when released from its bolt-fastening, all

constructed and adapted to operate substantially in the manner and for the purposes described.

2. The combination of a screw-threaded bush, a cupped seat thereon, a ring-cover .hinged thereto, a spring for lifting said cover,

and a spring locking-bolt therefor, all constructed and adapted to operate substantially in the manner and for the purposes described.

In testimony that I claim the foregoing as my own I aflix my signature in presence of two witnesses.

, I, G. NEISENTDORFER.
